WINDOW CONSTRUCTION.

Application filed July 30. 1923. Serial No. 654,665.

To all whom it may COIbG67"/b.'

Be it known that T, PAUL J. BROWN, a citizen of the United States, and a resident of North Olmsted, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Window Construction, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

This invention relates to an improved window construction. More particularly it comprises a window construction having guide members co-operating with grooves formed in the sash whereby a window in stallation of few parts and simple construction is provided and one which at the same time is rattle-proof and a full protection against the weather.

In addition to being constructed of a relatively small number of parts, the window sash, guide members and latching device have been found to be of extremely durable character and to work well when subjected to severe usage, as in automobile busses.

Heretofore metal window sashes, particularly designed for use in vehicles, have included guide members with additional resilient devices to make the structure weatherproof and to provide against vibration and noise. Such constructions have been relatively expensive and require very accurate application to the window frames to prevent such windows from becoming inoperative and jamming when subjected to rough usage.

The principal object of the present invent-ion is to simplify window construct-ions, particularly metal window constructions, for use upon vehicles and to include as integral parts of the guide strips themselves a resilient construction which will serve to prevent vibration and noise and at the same time provide a small degree of flexibility which will compensate for slight errors in accurate alignment of the parts. A further object of the invention is to so form a single strip of sheet metal as to provide the same with a rack section, frame engaging elements, a beaded guide member and a resilient portion so that a multiplicity of parts is avoided and yet every necessary function of said guide and fastening element provided for. Other objects of the invention will appear in the course of the following description.

The window as illustrated embodies features particularly adapting it for use in auto bus bodies, railway cars and street cars, but it is to be understood that such showing is not intended in any manner to limit the scope of the invention as set forth in the claims. To the accomplishment of the fore going and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing Fig. 1 is a front elevation of the window sash and guides applied to a window frame; Fig. 2 is a horizontal sectional view showing a frame member between adjacent win dows with the attached guides and channeled strips; Fig. 3 is a fragmentary side elevation of one of the guide members; Fig. at is a vertical central sectional view show ing the top and bottom members of the sash with the rubber cushion strips inserted therein; and Fig. 5 is a horizontal sectional view similar to Fig. 2 showing a curtain guide strip applied to the window frame.

As is clearly shown in the drawing, the window comprises a sash 1, preferably formed of sheet metal provided with grooves 2 at each of its vertical sides, said grooves being of slightly more than semi-circular ransverse section in order to partially embrace the beaoed edge of the guide members hereinafter to be described. The frame may be built up of pressed metal strips appropriately channeled on one side to engage the glass of the window and provided upon the opposite edge with grooves of somewhat more than semi-circular transverse sectional extent. These grooves 3 on the upper and lower sides of the window sash are adapted to receive rubber cushion strips 4, 5, having a rib or bend 6 of somewhat more than semicircular extent upon one side. Where applied to the under side of the sash the outer face of such strip is appropriately shaped to engage the adjacent sill 7 and when applied to the upper side of the sash of the window frame such strip is suitably formed to serve as a,wea,ther strip against the stationary part adjacent the upper edge of the window when the same is in closed position. (See Fig. 4:.)

These channeled strips may be mitredat their ends and joined in any preferred manner, as by brazing, spot-weldingor ot-her wise. When the device is to be used upon a vehicle such as amotor bus, there is pref? era bly provided adjacent each of the lower cornersof the. sash upon the inner side of thepwindow a, pairof latch members comprising a stationary. body plate 11 adapted to be secured to the frame and provided with an inwardly projecting finger piece 12, and a dog 13, provided with an integral finger piecielfpivotally, mounted upon said plate and lield in projected position by means of a spring. 15 coiled aboutsaid pivot pin 16 and engaged at its ends with said plate and dog, respectively.

The. guide members which, as has been indicated, cooperate to engage with the grooves ate-sch side v of the sash, are preferably, sl1eetmetal strips 21 of a length approx mately twice the height of the window sash. These strips are provided at one edge with a bead 22 of substantially circular crossrsection formed by wrapping said edgeabout ametal bar 23 of small diameter. Thebpposite edge of saidinbripv is provided with v a flat marginalportion 24, into the lowe1 portion of which a series of rack teetli ,,25 are. impressed to co-act with the dogs of the latches heretofore referred to. A series of holes for fastening screws 26 are proyid ed,;such holes being placed at intervals throughout the length of the strips and betweentlie rack teeth to provide means for securing said strips to, a wooden window frame, VVhen thestrips are to be secured to a metal window frame, suitable bolts may be used at intervals along said strip.

in the construction illustrated the flat portions of the stripsare secured to the insideof thejwindow frames and said strips arej provided, with a curved or bent portion 31 formedalong a linebetween said flat portionsand the beaded. edge heretofore re-v ferredto, in order that said beaded edge may projectatsubstantially right angles to said flat portion; when so formed,the curved portionsfil of the strips are spaced a slight distance from thewindow frame and said, inter iediate portion thus acts as a resilient or spring support for the window sash, prewntiug vibration and noise, and through the resiliency, and flexibility of said part preijenting jamming or interference with the freesliding motion of the window.

is has beenindicated, the rack portions of the stripsare adapted to be engaged by the projecting ends of the dogs when the sash is. in place upon thev beaded edges of the guide members; By grasping the finger projections upon the plate and dog; of the latch at either side of the window, the dogs may be retracted and the window shifted to the position desired, whereupon the release of said finger pieces will permit the re-engagement of said dogs with the adjacent rack teeth.

As is clearly shown in Figs. 2 and 5, when the device is applied to a vehicle such as a motor bus, it may be found desirable to place upon the outside of each frame mem ber 80, between the adjacent windows, a flanged metal channel member 7320f a size adequate to embrace said frame member and position said flanges 33 in slightly spaced relation to the outside of said outside. surface of the sides of the sash. Upon the inside of said frame member a wooden strip 34 may be fastened, said wooden strip being channeled on its inner face so as to permit its lateral edges to overlap the edges. ofthe flat portions of the guide strips secured to the opposite sides of said frame member. Thus, when the window construction is fully assembled, a complete and finished appearance will be produced.

When it is desired to provide for curtains at the windows, a sheet metal. strip d1, formed with a flat outer surface and lateral guide grooves 42 at eachside and a wide. channel-way 43 upon its interior face be: tween said lateral guide grooves, may be secured to the inside of said frame members in place of the wooden member heretofore referred to.

From the above description it will be apparent that the window construction provides a simple, durable structure capable of being easily applied to the window frame and adapted to serve as an adequate protection against the weather, as well as to withstand severe handling when the window is raised or lowered. These features are of particular importance when the construction is used upon vehicles, such as auto busses, street cars and railroad coaches, especially the providing of a free, resilient section as an integral part of each guide strip. for use on boats and may be applied to houses and cottages where light weather-proof construction is found desirable.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of suchpsta'ted means be employed.
